Apart from these organizational designs, there are a number of other logistical organization structures which can be employed by small to medium-sized businesses or by businesses with a small volume of logistics tasks. By establishing a central staff unit, it is thus possible to coordinate the flow of goods and materials centrally without having to set up a new department. In these cases, however, the management responsibilities are given to other functional areas such as production or sales. That is why staff units may often only have a say by virtue of their methodical and professional competencies as for instance budgeting or simulation calculation, cost-benefit analysis, or key figures development. The same is true for expert panels (conferences, committees, meetings) and teams that assume advisory functions and/or perform preparatory work for decision-making. Teams are especially suitable for collaborative and temporary tasks and projects.
